Alright all, it's been a while so sorry to come back asking boring questions rather than with something Interesting! Right my ****** car is doing my head in, it won't communicate with vcds, well it will talk to abs module on a good day but that's it! Engine module just says no response from controller, which is annoying me as I need to do some logs. So far I've ripped out half the dash to check on the k line and any connection's and all is fine. Must be getting power and be an earth as its talking to abs and powering up the ross tech cable. Aftermarket stereo is unplugged and k line correct there too. Any ideas? All constructive suggestions appreciated
